  3. What does it mean to evaluate an expression? When you evaluate a numerical expression, you find its value or answer.

  4. Identify the order of operations. Steps: • Parentheses • Exponents • Multiply or Divide from left to right • Add or Subtract from left to right

  5. Example 1: Evaluate each expression. • 9 + 12 x 2 no parentheses no exponents 9 + 24multiply 33add

  6. Example 1: Evaluate each expression. (B)4 x 32 + 8 - 16 no parentheses 4 x 9 + 8 -16 exponents 36 + 8 -16 multiply 44- 16 add 28 subtract

  7. Example 1: Evaluate each expression. (C)8 /(1 + 3) x 52 - 2 8/4 x 52 - 2 parentheses 8/4 x 25 -2 exponents 2 x 25 - 2 divide 50- 2 multiply 48 subtract

  8. Example 2: Regina bought 5 carved wooden beads for $3 each and 8 glass beads for $2 each. Evaluate the following expression to find the amount Regina spent for beads. 5 x $3 + 8 x $2 no parentheses no exponents $15 +$16multiply $31add
